x402 Agent Payments

The gateway supports HTTP 402 payments for premium tools. AI agents can autonomously pay for:

• Advanced analytics queries
• High-frequency price feeds
• Premium security scans
• Priority transaction submission

Payment flows through Sperax USDs on Arbitrum for auto-yield benefits — your payment balance earns 8-25% APY while waiting to be spent.
